Forte Diamante is one of the top sights in Genoa for travellers who enjoy panoramic viewpoints, rugged landscapes, and stories of military strategy. Perched at 667 metres above sea level, it crowns the ridge between Val Polcevera and Val Bisagno, forming part of the city's formidable defensive system. Though the interior is no longer accessible, the fortress remains an evocative landmark, surrounded by nature and layered in history.

It is also a great place to visit on a walking tour of Genoa's hills, particularly for hikers making their way along the Forti di Genova trail. The journey to Forte Diamante, with its sweeping views over the valleys, mountains, and coastline, reveals why this stronghold was once vital to the city's protection.

History and Significance of Forte Diamante, Genoa

The site atop Monte Diamante has been associated with military activity since at least 1395, when records mentioned the “Bastia del Pino,” an early defensive position. Its strategic importance grew significantly during the Austrian siege of 1747, prompting the creation of a star-shaped palisade redoubt to protect the surrounding valleys from incoming attacks.

In 1756, the Republic of Genoa formally commissioned the construction of a major fort on the mountain, guided by Engineer Jacques De Sicre with contributions from Robert de Cotte and Marshal Antonio Federico Flobert. Despite delays caused by land disputes, the project progressed thanks to the persistence and financial support of Marquis Giacomo Filippo Durazzo. Forte Diamante was completed in 1758.

The fortress underwent multiple modifications throughout its lifetime. The original pitched slate roof was replaced with a defensive terrace during the Napoleonic period, and 19th-century enhancements by the Kingdom of Sardinia added machicolations, expanded barracks, and a semi-circular tower with a spiral staircase. The fort played a critical role in the 1800 battle between French defenders and Austrian forces led by the Count of Hohenzollern, holding firm despite a fierce siege.

By 1914, Forte Diamante was abandoned as a military site. While the structure has since deteriorated, its imposing silhouette and historic legacy endure as powerful symbols of Genoa's once extensive defensive network.

From the hilltop, you can gaze across the Ligurian Apennines, the city below, and the distant shimmer of the Ligurian Sea. Photographers and hikers alike find the panorama one of the most rewarding in the region.

Although the interior is closed to the public, the exterior remains impressive. The sturdy stone walls, bastions, and distinctive profile reveal the architectural evolution of the fort across centuries-from Genoese design to Napoleonic adaptations and Savoy-era improvements.

"A great hike! Not very well marked but google maps shows you where to go! The view is beautiful and being able to climb into the forte to see theinside added a fun element!..."

"The direct hike that leads up the hillside is definitely invigorating and requires supportive athletic footwear, but it is much closer to 30 minrather than the posted 40 min. Park near the charming and well-menued trattoria, use the restroom and maybe grab a snack and a beverage beforehand if you didn't bring any (or definitely di er after). A truly beautiful way to spend a few hours on a clear and warm day...."

"I went with my family for our first hike while in Genoa. My kids are 7 and 11 years old. We had not so warm day which was just perfect. We couldn'ttake the train to Trensasco due to work but took bus replacement instead. The initial climb was steep but manageable. We explored the grounds around as didn't want to risk wild climbing with kids to the very top of fort. I think we would have to use some cleverly placed scaffoldings etc to do that. Afterwards, we climbed down via zigzag pathway towards train in Righi. It took us a while as at few times path was tricky to follow but there are works going around and occasionally we met ru ers and dog walkers and mountain cyclists so there are chances to chat if you feel lost a bit or just unsure which path to take. That day was the best day in our kids' eyes, forget boat trip, gelato etc now they want to hike again...."
